I receive telephone calls from the number 425-977-2020 daily, sometimes up to three calls. There is no business name and they leave no message. I personally make a practice of not answering incoming calls from unfamiliar numbers. I will take the next incoming call from them and if who ever it is will 'kindly' be asked to stop calling and remove my name from their calling list. This type of practice of calling clients, or potential clients and not leaving a message nor flashing a legitimate business name as their caller presence - should be changed in the name of business ethics.
I also have been phone calls from number 425-977-2020 and they never leave a message. I am tired of this kind of phone bullying. If it is Penguin Windows then they are behaving in an unprofessional manner and I would not purchase from them.
If this is Pinguin Windows then it makes sense (finally)! I too have been getting calls every day from this number...reading this post makes sense. I signed up for a promotional "contest" at a store the other day, where the winner could get a new kitchen (or whatever). I gave them my phone number to call if we won (silly me...they were using the contest as a disguise for capturing suckers).
